Patent number: 6054662Abstract: A return device for an electronic system push button. The return device includes a torsion bar for storing torsion energy when a push button is moved from a non actuating position to an actuating position. The return device includes an arm extending from the torsion bar for receiving a user generated force on the push button and for providing a return force for the push button. One end is rotatably coupled to a housing panel and the other end is coupled to the panel to restrict rotation of the end with respect to the housing. In one example of a return device, the push button and an actuator are fixably coupled to the arm. The return device can be used with a variety of push buttons which perform different operations for an electronic system. For example, a return device may be utilized with a push button that actuates a panel retention mechanism of a housing.Type: GrantFiled: April 26, 1999Date of Patent: April 25, 2000Assignee: Dell USA L.P.Inventors: Robert D.

Patent number: 5954191Abstract: A mechanism (10) for actuating an electric circuit is disclosed including a cover (124) having a front wall including a broad surface and movably mounted by pins (126) extending through apertures (108) formed in a mount (90, 90') of a housing (12, 12'), with the cover (124) being biased by springs (130) located on the pins (126). Tongues (136) of the cover (124) engage the legs (118) of first and second actuating arms (112, 114) to pivot the arms (112, 114) to pivot an actuation lever (100). The lever (100) includes an actuation finger (104) which pushes against the toggle (38) of a switch (36) to de-energize the circuit. Thus, when any point of the cover (124) is pushed towards the mount (90, 90'), the switch (36) is moved to de-energize the circuit. A switch lever (70) is pivotably mounted to the housing (12, 12') and is pivoted by a slideable actuator (42) to move the switch (36) to energize the electric circuit.Type: GrantFiled: August 8, 1997Date of Patent: September 21, 1999Inventor: John P.

Patent number: 5947267Abstract: A switch assembly which has a mount (12), an elongate member (14), a switch (16) and a fulcrum (18). Pressing on elongate member (14) provides a force to actuate switch (16). Elongate member (14) is resilient or, alternatively, is resiliently biased to return to an unactuated position. Fulcrum (18) is movable along a length of elongate member (14). Positions of fulcrum (18) along the length enables variation of the force to actuate switch (16). As a result of this variation, different tactile feel of the switch assembly can be provided depending on position of fulcrum (18) relative to switch (16). Fulcrum (18) can also be positioned along elongate member (14) to provide a locking position that prevents switch (16) from being actuated.Type: GrantFiled: November 21, 1997Date of Patent: September 7, 1999Assignee: Motorola, Inc.Inventors: Cheah Chan Kee, Seong Jin Lim, Hari Narayanan S/o P.

Patent number: 5911316Abstract: A device for manually turning-on at least one circuit-breaker from the front panel of a cabinet includes at least one sleeve having a front end and a rear end. The sleeve extends through an aperture in the front panel and is movable between a backward position, in which the front end of the sleeve projects slightly from the front panel, and a forward position, in which the front end of the sleeve projects away from the front panel. A spring is compressed to push the sleeve from the forward position to the backward position. A rod is operably connected to the sleeve so as to be displaced following the forward movement of the sleeve and to remain in its position uneffected by the backward movement of the sleeve.Type: GrantFiled: August 17, 1998Date of Patent: June 15, 1999Assignee: Acbel Polytech, Inc.Inventor: Chien-Ming Chu

Patent number: 5900584Abstract: An enlarged cover plate assembly is used with a conventional electrical wall switch having a rotatable rocker arm within a mounting bracket with threaded mounting holes with a spacing for conventional cover plates. An enlarged cover plate has an area substantially greater than the area of the wall switch and has a front surface forming a decorative surface and a back surface facing the wall switch. The cover plate further defines an aperture connecting the front and back surfaces and having a length less than the distance between the mounting holes. The enlarged cover plate is attached to the switch mounting bracket. Two flanges extend between the back surface of the enlarged cover plate and the wall switch and are oriented so that the rocker arm moves parallel with the flanges.Type: GrantFiled: May 6, 1997Date of Patent: May 4, 1999Inventors: James L. Cady, Philip O. Brady

Patent number: 5850613Abstract: Apparatus for a radio microphone enables hands-free operation of the microphone when it is attached to a user's shirt, jacket or other article of clothing, for example. The apparatus preferably comprises a cover which is attached to the microphone and includes an integral actuating lever that is positioned to be actuated by movement of a user's head or chin. Police, fire or other emergency personnel at the scene of an emergency can utilize the cover to keep their hands free for other tasks during operation of the microphone, and this also avoids the possibility that the user will contaminate the microphone by contacting it with their hands.Type: GrantFiled: July 30, 1996Date of Patent: December 15, 1998Inventor: David C.

Patent number: 5813520Abstract: An actuator button is mounted in a housing by a cantilevered beam fixedly attached to the intermediate portion of a torsion beam. The ends of the torsion beam are nonrotatably fixed with respect to the housing. The actuator button is maintained at a normal, spaced-apart position with respect to a switch positioned within the housing. Movement of the actuator toward the switch induces bending stress in the cantilevered beam and torsional stress in torsion beam. The actuator button arrangement permits direct, vertical insertion of the actuator button into the housing, does not require any secondary assembly operations, and has a unitary construction.Type: GrantFiled: July 17, 1997Date of Patent: September 29, 1998Assignee: Ericsson, Inc.Inventors: Bart Reier, Patrick Nixon, Robert Doran
